New material cutout implementation

[yaustar]

@Mirko_Arcese

Or maybe i didnt explain my self properly, using the alpha we dont obtain a coloured border which instead is obtained with “burn shader”, but this last will not work on transparent material.

If you go to the last post, I believe I did it here: How can I make the custom shader stop? - #22 by yaustar

If you need it to not be affected by lighting, I think if you include the emissive chunk, you can change the color there?
